Anna Heinrich’s mind-blowing bikini

Currently in Byron Bay with hubby, former Bachelor Tim Robards, the blond-haired beauty posted an Instagram snap of herself posing in what appears to be a striped, nautical red-and-white bikini. But all is not as it appears.

"Spot the dots. Do you only see stripes?" she wrote alongside the post.

Commenters appeared confused, with one asking: "Are the stripes made of tiny polka dots? "This kind of thing can keep people up at night."
